PUMP.

SPECEICATION forming part of Letters Patent No. 328,146,6.ated October 13, 1885.

Application filed December 2T, 1884. Serial No, 151,335. (No mode.)

To all whom, it may concern,.-

Beit known that I, ABIEL L. RUssELr., a citizen of the United States, residing at Roninlns, in the county of Seneca and State of New York, have invented certain new and useful` Improvements in Pumps; and I do hereby declare that the 'following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to plnngers for suction, force, and lifting pumps; and it has for its object to provide the same with imi roved means whereby,when the packing has become worn to such an extent that it will not free the vacuum in said pipe, that such wear may be compensated. f

A further object of the invention is to improve the details of construction and to pro vide a plunger which shall be simple iu its construction, effective in its operation, `and one that may be manufactured at a comparatively slight cost.

The invention consists in the improved construction and combinations ot' parts, hereinafter fully described, and pointed out in the claim.

1n the drawings, Figure l is a side elevation of my improved plunger. Fig. 2 is a longiA tudinal vertical section of the same. Fig. 3 is a-perspective view of parts detached.

In the accompanying drawings, in which likeletters of reference indicate corresponding parls in all the figures, A represents the plunger, whirh consists of two sections, B C. The section B is reduced at one end, thus forming a shoulder, c, said reduced end of the section B being exteriorly threaded, as shown. Fitting upon said reduced threaded end of the section B, and resting upon the shoulder thereof, is a rubber washer or washers, b.

The section G is interiorly threaded at one end and receives the threaded end ofthe section B. It will thus be seen that when said sections are tightened they will compress the rubber washer or washers and expand the same. It will also be obvious that by the e1nployment of rubber in lieu of leather, which has ordinarily been used, a packing is provided which is thoroughly impervious to water, therefore more lasting, for the reason that does not destroy the life of the same.

water Fitted upon the threaded extension B are leather washers ci, which are iiat or plain npon their inner faces and convex in form upon their outer faces, said washers being lo` cated on ea ch side of the rubber gasket or packing. By the employment of these washers, when the sections are tightened, said packing can be more easily expanded when it has become so worn as to be unfit for use.

The section C is provided with a series of elongated openings, c, of which `there may be as many as desired or found necessary. Said section C is also provided at its other end with a screw-threaded opening, d, for the reception of the plnngerrod, which is attached to said section. The under side ot the top of the section C is so constructed as to be bellshaped or concave in form. as shown.

The section B is provided on its inner side, adjacent to its threaded end, with an inwardlyextending circnmferemial flange, di, the face of which is concave, thus forming a concave seat, d3. The inner walls oi' said section also incline or slope toward said seat.

Fitting in the opening or chamber of the upper section of the plunger isa valve, D, said valve consisting of a disk, c, having a convex upper face and a stem, f, projecting downwardly from the under side of said disk, said stem being adapted to fit in the opening at the upper end of the lower section, t-he disk resting on and closing said opening.

E represents the check-valve,which consists preferably of a circular strip of rubber having projecting ears g, provided with holes or openings for the passage of screws or their equivalent for its attachment. rlhe circular strip of rubber of the valve E is recessed or cut away, as shown at h., to form the hinged portion i, which is provided with a central perforation or opening. Upon the upper side of the hinged pieceil is provideda meta-l disk, j, while upon the under side of said piece z' is a somewhat smaller disk, c,said disks being provided with central openings to register with the opening of the piece Upon the upper side of the disk j is hinged, by means of a strip of rubber, k2, a valve, Z, having the extensionpiece m.

rlhe pipe G, in which the plunger and valve E are located, is composed of two sections having iianges a at their meeting ends. The

circular strip of rubber having the projecting earsfg is fitted between the iianges of the pipe, the rivets or bolts securing said sections together passing through the openings in the ears g, the hinged portion z' tting the pipe and being held tightly therein against nuovenient.

The operation is as follows: Supposing the plunger to be lowered, the same is raised, which opens the valve Z and draws the water into the upper pipe. lowered, the water passes through the coneshaped passage of the lower section of the plunger and forces the valve D from its seat, the water passing' through the elongated openings ofthe upper section, the rubber packing between the sections of the plunger preventing the backward iiow of the Water.

I claim as my invention and desire to secure by Letters Patent- Vhen the plunger isV ARIEL L. RUSSELL.
